I'm making a reference to an earlier post or two - -
I was rummaging about the intertubes this afternoon and stumbled upon this article from Politico by Bruce Blair - one of the signatories of the letter on why Mr Trump should not have his finger on the "nuclear button."
It's lengthy, but provides a pretty good primer on the process and procedure of how nukes are committed. Many of the statements bring back memories, and from my background and hands-on experience are accurate - and frightening.
Mr. Blair is featured in this ad for Hillary Clinton that was filmed at the Park Service site where I volunteer.
